目的 了解张家口市水碘的分布情况，为碘缺乏病防治提供基础资料和科学依据。方法 在张家口市以乡为单位．按东、西、南、北、中5个方位各选取1个村，每村采集1～5份水样，采用砷铈接触法测定水碘。结果 调查了17个县（区）213个乡（镇）1059个村庄，检测饮用水样2364份，水碘范围（0．03～428．55）μg／L，中位数为4．58μg/L，其中水碘〈10μg／L的占78．93％；依据国家标准在213个乡（镇）所在地（乡级水平）中未有高碘地区．在村级水平只有4个高碘村，占总村数的0．19％。结论 张家口市主要为碘缺乏地区，存在少数高碘村。
Objective To investigate iodine concentration in drinking water in Zhangjiakou City and to provide basic data for the prevention of iodine deficiency disorders in this area. Methods Each village in the east, south, west, north and the middle of every township was selected in Zhangjiakou magistracy area, and 1 - 5 water samples were collected in each sampled village. Iodine concentration was determined by arsenic-cerium contact methods. Results Among 1059 villages in 213 townships of 17 counties investigated, 2364 water samples were collected and tested. Median iodine content was 4.58 （0.03 - 428.55）μg/L, with 78.93% samples within the scope of 〈 10 μg/L. According to the country standard, no areas had high iodine in water in the 213 townships, except for 4 villages had high iodine, accounting for 0.19%.
